中文摘要：面对一些航空航天三通管件毛料厚度薄，成形后厚度要求高，结构复杂等难于成形特点，本文开展了三通半管拉深成形过程的研究。运用PAMSTAMP模拟软件研究不同参数下半管成形后的厚度和质量，分析了凹模圆角半径、凸凹模间隙、压边力对零件成形质量的影响，并获得了最优的工艺参数。用于指导生产，降低了生产周期和成本。
英文摘要： The drawing process of half-three-way tube is investigated in this paper because of facing the difficult forming characteristics of some three-way tubes in aerospace craft, for example, the thin thickness of material thickness, the high request on thickness of product after forming, and the complex product structure. The thickness and quantity of half-three-way tube with different drawing parameters are studied by simulating using PAMSTAMP. The influences of round corner radius of the cavity die, the clearance between punch and die and blank holder force on product forming quantity are analyzed. The superior drawing parameters are acquired. The produce period and costs are reduced by using the superior drawing parameters.
